IRH-01F & IRH-01R
Both front and rear IRWIN Road Hubs contain ceramic bearings. Strategic placement of these bearings in relation to flanges (bearings offset flange) reduce stress and impact on the bearings whilst the wider flange to flange width provides better lateral wheel stiffness these features combine to improve hub durability. The Hub shells undergo a special forging process to strengthen the hub structure and the precise CNC machining process ensures a perfect bearing bore improving durability further. The unique design allows for an easily interchangeable cassette body compatible with Campagnolo 11-speed eliminating the need to change bushing or end cap.The free hub utilises a 6 pawl and 60 ratchets system, this facilitates a faster and smoother engagement, translating into more efficient power transfer.
